- Bulletin 339 MGT - Solving the Impossible 1/2
- Release date: August 15, l994
-
- Experience can be a very hard teacher at times. One such
- experience that leaves a lasting impression on emergency
- personnel is that there is never sufficient communications
- capability in a major disaster situation, especially in the
- earliest stages. As a result, forward looking government
- emergency response agencies have learned to use trained volunteer
- communicators to supplement their full time resources from the
- onset of the situation, just as they do volunteer fire and law
- enforcement personnel.
-
- However, a major principal involved in this process is
- that the effectiveness of the communicators is in direct
- proportion to how well they have been trained by and integrated
- as part of the parent government agency. The emergency
- communications reserve cannot be "created and then left to
- flounder". Its key personnel (the radio officer and assistants)
- must be thoroughly familiar with the day-to-day affairs of the
- agency. They are similar to other employees, albeit unpaid, in
- that they must know IN ADVANCE what is expected of them and how
- things are to be done. In an emergency there will be no time or
- personnel to bring them up to date on agency procedures,
- processes and expectations. Ideally, the only difference between
- the unpaid volunteer and the paid staff is the volunteer's unpaid
- status and the intermittent nature of their utilization.
-
- Although unpaid communicators are an expense to the
- parent agency (in that their familiarization and supervision
- involves both time, energy, space and equipment) in literally
- thousands of major emergencies the cost of insuring an effective
- reserve for the next major emergency is minuscule when compared
- to their often priceless contributions to an effective emergency
- response. They have made a hero of the emergency management
- agency in countless situations with selfless dedication to
- providing communications that was otherwise considered to be
- "impossible".

- RACESBUL.337 SUBJECT: TEC - Why Packet Radio?
- RELEASE DATE: August 1, 1994
-
- QUESTION: Is it important, or necessary, to have packet
- radio?
- RESPONSE: Yes, with packet radio (digital data) you can
- access a world of data you may never achieve in any other way.
- For that reason, it is recommended that every EOC and/or
- communications center have a packet radio terminal, which
- consists of a radio, a terminal node controller, and a digital
- communications terminal (computer) and printer. Once the unit is
- operational and accessible to a local bulletin board system
- (BBS), it can be left on all the time so that any traffic
- addressed to RACES will be automatically transmitted to
- unattended government terminals. A licensed Amateur Radio
- operator does not have to be in attendance to RECEIVE traffic.
-
- Also, keyboard-to-keyboard communication is quite usable
- in emergency and temporary communications systems where it can be
- accomplished either direct or through no more than one mountain
- top relay. A good volunteer communications unit can put such a
- relay (digipeater) where none normally exists for the duration of
- the emergency. A good communications unit is one that can
- establish an emergency system that is never dependent upon
- individuals or their call signs. The people may come and go but
- the system must stay in place until demobilization. Just make
- sure the system will remain intact for the duration of its need
- and that it is not dependent on the presence of a particular
- person.
-
- Packet radio has earned its highest praise during major
- incidents like forest fires, earthquakes, floods, etc. California
- State OES volunteers regularly issue one or more SITREPS
- (situation reports) daily to all affected agencies and
- jurisdictions. It is transmitted via the Amateur Radio packet
- system to all packet Bulletin Boards in the Western United
- States. Many fire departments, for example, rely on these
- updates.
-
- Necessary to the overall formula for success is a state
- emergency management agency committed to actively promoting,
- using, and providing ongoing management and leadership in the
- utilization of communications volunteers in government service.
- Unfortunately, not all states support and participate in this
- role. However, our experience proves that the cost is extremely
- low for the benefits derived. Packet radio communications has
- been just one of them.

-
- faisyn20.zip Electronic Filter Synthesis Program
-
- FAISYN is a low cost, effective alternative to expensive commercial
- filter synthesis packages. The program has be used to design lumped
- element filters and diplexers from 10's of KHz to 1.5GHz and is the
- result of many years experience in filter design. Designers know
- that filter design is often an iterative process. Tedious number
- grinding is sometimes required to optimize a design. FAISYN eases
- the burden by allowing the designer to quickly synthesize a variety
- of circuits that can be simulated and compared using your favorite
- circuit simulator (FAISYN currently supports PSPICE-TM Microsim,
- MMICAD-TM Optotek and TOUCHSTONE-TM HP/EESOF circuit formats).
-
- Special Requirements: None
-
- Shareware.
-
- Faisyn was developed by:

-
-
- You can get FAISYN20.ZIP from one of the following sources:
-
- 1. I just posted a UUENCODED version (2-parts) to comp.binaries.ibm.pc
-
- 2. I have just uploaded the program to the SIMTEL collection. It
- should appear there, and on it's mirrors soon in /msdos/electric.
-
- 3. I tried to upload it to bode.ee.ualberta.ca, but for some reason
- it appears to be down today. Look for it there soon.

- RELEASE DATE: July 25, 1994
-
- It takes an unusual volunteer to provide dedicated and competent
- service to emergency management agencies, EMA. Such volunteers
- must be ready to appear on short notice, stay at their assigned
- post and duties until relieved, be willing and able to travel
- where needed. They may even provide the necessary equipment at
- their own expense. They cannot be "amateurs" in the sense of
- pursuing a hobby. Instead they must devote a great deal of time
- and energy to become as proficient as paid staff. The agency they
- work with must be able to depend upon their availability when
- needed, their skill at assigned tasks, and their ability to mesh
- into the overall disaster response exactly as is expected of paid
- staff. Fortunately there are people, ready, willing and able to
- serve in such capacity.
-
- Such a pool of qualified volunteers is a resource, the value of
- which often becomes overwhelmingly evident when a major emergency
- threatens to exceed the capabilities of paid staff and equipment.
- Like any other resource, volunteers must receive adequate
- training, needed facilities, and the attention and general upkeep
- that is accorded any other resource. Recognition of the
- contribution to the tasks at hand should be as professional as
- anything else in the relationship. As with any staff, they respond
- to honest reassurance that their work is recognized and respected;
- however, their service will be quickly lost if they are merely
- tolerated, or seen as a nuisance.
-
- If the EMA makes a positive effort to integrate this nominally
- "free" resource, allocate time, energy, and people to use it to
- best advantage, provide its necessary resources, and develop it as
- they do with any other resource, it develops a relations hip with
- an open ended potential. It also extends agency capabilities in
- many directions while providing satisfaction to the volunteers
- for their time and efforts.

-
- These bulletins serve multiple purposes both for the
- civil defense or the emergency management agency and the program
- participants.
-
- For the agency a major purpose is to assist it in the use
- of emergency communications volunteers as unpaid staff. How to
- best use them can be very satisfying. Having qualified extended
- staff (albeit it unpaid) can provide astonishing benefits to the
- agency and the community.
- Material and other assistance about this is available
- upon request. Assistance includes on-site seminars for local
- government, the emergency management agency and the program
- participants. Materials range from policy and guideline
- suggestions to actual emergency communications plan preparation
- customized to the local needs. A particularly valuable resource
- is the State OES manual "Establishing and Maintaining an
- Emergency Communications Reserve", which is based on the
- information bulletins to Emergency Management Agencies issued by
- the Auxiliary Communications Service from l985-1993. [Free to
- California jurisdictions. Others may request a copy with a $12
- check payable to the State of California. ]
-
- For the program participants a major purpose is to discover how
- to function as "unpaid staff" of the agency alongside the paid
- staff; i.e., how to become an integral part of the agencies
- day-to-day activity. How to benefit both the participant and the
- agency by skills other than "just operating a radio", and the
- unheralded rewards and deep sense of a worthwhile contribution
- that ensue. With the expansion of Public Safety communications
- systems there is a real need for augmentation of staff (albeit
- unpaid) capable of providing maintenance and operation of these
- systems during extended emergencies. The use of Public Safety
- systems by program participants can range from augmenting 911
- systems to the emergency installation, maintenance and operation
- of local government radios.
-
- One example of such an integrated emergency
- communications program is illustrated by the publication "State
- of California Governors Office of Emergency Services Emergency
- Communications Reserve, the Auxiliary Communications Service".
- How it is implemented and designed is set forth in the 1994 plan
- of the same title distributed to California counties and State
- and Federal agencies without charge. Others may request a copy
- with a $11 check payable to the State of California. Mail to
- Office of Emergency Services, ACS Program, Telecommunications

- work extremely well at MF (160-meter country) because of the low reflection
- angles that those frequencies have from the ionosphere.
-
- See also the ARRL Antenna Book, which devotes a significant amount of
- coverage to wave antennae.
-
- (N.B. - I always thought it was spelled Beveridge, but that's not the
- way it is in the ARRL book... oh, well, ya learn something new every day!)

- Subject: Which code learning method? Why?
- To: info-hams@ucsd.edu
-
- I'm intrigued about the methods of testing CW proficiency in the US. Is
- there both receive and transmit testing?
-
- In VK, we sit both. The receive test is a straight copy-the-plain-language
- test. If you copy it with below maximum errors, then you pass.

- Now for a newbie question. What is "Farnsworth"? I am very confused
- as to how something can be 5WPM _and_ 16WPM at the same time. I am
- thinking
- of getting a tech plus and looking into learning CW.
-
- How do I learn code Farnsworth?
